Well, I am a layman and I don't think as a layman that I need to "understand" and this is why.
When the bible was written laymen in general didn't even know how to read. Therefore it was not meant for them.
The only people at the time who could read were Kings and Scribes.
THAT is for whom the bible was written.
As a layman with such simple thoughts and simple mindedness I feel that all I need to worry about is following the golden rule and accepting Jesus as my savior. All the rest is meant for Kings and Scribes...
The Golden Rule Part A: Do unto others as you would have them do unto you.
The Golden Rule Part B: The ones who have the gold make the rules.
Have fun enlightening me...
